The Convent Threshold Christina Rossetti

There's blood between us, love, my love,
There's father's blood, there's brother's blood;
And blood's a bar I cannot pass:
I choose the stairs that mount above,
Stair after golden skyward stair,
To city and to sea of glass.
My lily feet are soiled with mud,
With scarlet mud which tells a tale
Of hope that was, of guilt that was,
Of love that shall not yet avail;
Alas, my heart, if I could bare
My heart, this self-same stain is there:
I seek the sea of glass and fire
To wash the spot, to burn the snare;
Lo, stairs are meant to lift us higher:
Mount with me, mount the kindled stair.

        Your eyes look earthward, mine look up.
I see the far-off city grand,
Beyond the hills a watered land,
Beyond the gulf a gleaming strand
Of mansions where the righteous sup;
Who sleep at ease among their trees,
Or wake to sing a cadenced hymn
With Cherubim and Seraphim;
They bore the Cross, they drained the cup,
Racked, roasted, crushed, wrenched limb from limb,
They the offscouring of the world:
The heaven of starry heavens unfurled,
The sun before their face is dim.
